BOLSTER GUIDE-BAR FOR CAR-TRUCKS.

SPECIFICATION forming part of Letters Patent No. 437,722, dated October'7, 1890.

Application led J' annary 24, 1890. Serial No.337,980. (No model.)

To all whom it may concern:

Be it known that I, CHARLES T. SoHoEN, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented a certain new and useful Improvement inBolster Guide-Bars and Bolster-Guide-Bar Plates, of which the followingris a full, clear, and exact description.

The object of this invention is to produce, from pressed steelespecially, a bolster guidebar and a bolster-guide-bar plate forrailwaycar trucks.

The invention consists of a bolster guidebar and a bolster-guide-barplate constructed, by preference, of pressed steel, substantially in themanner hereinafter more particularly set forth and linally claimed.

In the accompanying drawings, illustrating myinvention, in the severalfigures of which like parts are similarly designated, Figure l is afront elevation, Fig. 2 a side elevation, Fig. 3 a top plan view, Fig. 4a bottom plan View, and Fig. 5 a cross-section taken in the plane ofline fr, Fig. 1, of the bolster guidebar. Fig. 6 is an elevation, andFig. 7 a longitudinal section, of the bolsterguide-bar plate; and Fig. 8is a perspective view of portions of a railway-car truck in outline withmy guide-bar and plate applied. Fig. 9 is a perspective view of amodified form of guide- The bolster guide-bar a is struck up in dies orby other suitable devices and from sheet or plate steel or other Wroughtmetal which maybe foundin open market, or may be made in shape to order.In order to obtain the requisite strength, this guide-bar is belliedcentrally, as at b, and, preferably, in the arcs of circles, asindicated in the sectional view, Fig. 5. The ends c may be squared andturned in to form heads, as at CZ and e, and these heads are providedwith openings f and g, respectively, for the passage of a throughbolt h,(shown in dotted lines in Fig. 8,) for connecting the parts with thebraces or beams of the truck. Side Wings i' are provided forco-operation with the bolster guide-plates. (Shown in Figs. 6, 7, and 8,and hereinafter more particularly described.) The Wings i' are enlargedat their lower ends to form liangesj, which are provided With bolt-holesto receive the bolts 7c, (see Fig. 8,) by means of which the bolsterguide-bar is secured to the truck.

The bolster-guide-bar plate Z (see Figs. 6,

7, and S) has struck up the parallel ribs m, which form Ways to receivethe Wings i of the bolster guide-bar and to guide the parts in themovement of the truck. Holes n are made in the guide-bar plate for thereception of fastening devices to secure the guide-bar plate to thetruck.

The parts are assembled as clearly indicated in Fig. 8. Very obviouslymodiications in the form of these parts will be made to suit therequirements of railway construction, and these I esteem as within myinvention so far as they contain the principle of my invention.

These wrought-ni etal bolster guide-bars and bolster-guide-bar plateswill be constructed so that they may be interchangeable with thecast-metal and other bolster guide-bars and guide-bar platesin commonuse, so that in repairing cars old bolts and old bolt-holes may beemployed in assembling my improved bars and plates. Another and manifestadvantage of my invention is the great difference in weight iu favor ofmy construction without any impairment of strength or durability, butrather in gain of both.

In the use of the term bellied, as applied to the longitudinal elevationof the bolster guide-bar, I mean to include any form or extent ofelevation of the metal which will strengthen the guide-bar. For example,the bellying may be angular, as indicated in Fig. 9, instead ofcurvilinear, and it may be in a single straight line instead of atinclinations.

What I claim isl. A pressed-steel or other Wrought-metal bolsterguide-bar having edge fianges for attachment to a part of the truck,bellied longitudinally and having terminal heads for the reception ofthe connecting-bolt,'and also having wings for (3o-operation with abolsterguide-bar plate, substantially as and for the purpose described.

2. A bolster guide-bar provided with basetlanges, Wings, and anintermediate bellied portion of curvilinear outline and terminating insquared end portions or heads and constructed of pressed steel or otherWrought metal, substantially as described.

In testimony whereof I have hereunto set my hand this 23d day ofJanuary, A. D. 1890.

CHARLES T. SCHOEN.
